An airliner flying from Havana to Milan abruptly plunged some 3,300 feet when it hit unusually strong turbulence over the Atlantic on Monday, terrifying passengers and leaving some 30 people aboard with bruises and scrapes, airline officials said. (seattletimes.com) 更多...

It was reported as a 767. There was convective activity in area but no reports that they flew into a cell or encountered svr downdrafts coming off anvil. Hope that they sanitized the seats after landing.

Bermuda Triangle strikes again? Didn't say if it was CAT which generally does not result if ever in a sudden loss of altitude with accompanying zero or negative G. Sounds more like penetration (inadvertent or otherwise) of convective activity which begs the question of whether weather radar was available and in use.

I'm positive wx. radar would be working on an airliner, especially one crossing the ocean. Most MEL's say the radar could be inop. as long as the route does not take it into an area of forecasted thunderstorms, which is unlikely over the ocean.

The thing is Thrust that many of the operators that do the S America to Europe runs are just on the very edge of the fuel regulations. The punters like direct flights. So if the weather radar means a deviation the PIC has to make a decision that is not solely based on safety. Now before God's people jump on me and tell me that I do not know the F of what I post I challenge those that do these trips to come clean.
